Kathy stood on middle rung of a ladder, she climbed up 5 rungs, than climbed down 2 rungs, climbed up 9 more rungs, and finally climbed last 4 rungs to top. how many rungs in the ladder?

33

Step-by-step explanation:

If she is in the middle of the latter just count how many rungs there are above the middle that will be the same number of rungs there are below the middle.

i dont know if you cant find a way its best to actually add all of them start from 105 tho

step-by-step explanation:

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
